CHAPTER 5: SETTINGS TESTINGC60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL 5-3075The relay must be in test mode to use the PMU test mode. That is, the TESTING TEST MODE FUNCTION setting must be“Enabled,” and the TESTING TEST MODE INITIATE initiating signal must be “On.”During the PMU test mode, the physical channels (VA, VB, VC, VX, IA, IB, IC, and IG), frequency, and rate of change offrequency are substituted with user values, while the symmetrical components are calculated from the physical channels.The test values are not explicitly marked in the outgoing data frames. When required, it is recommended to use the user-programmable digital channels to signal the IEEE C37.118 client that test values are being sent in place of the realmeasurements.The UR Synchrophasor Implementation defines a test mode that sends a pre-defined set of synchrophasors out over thecommunication channel when the test mode function setting is enabled. In test mode, the following actions take place:• The Data Invalid / Test Mode bit (bit 15 in the STAT word) is set• The Sim bit in all output datasets is set5.11.4 Force contact inputsSETTINGS TESTING FORCE CONTACT INPUTSThe force contact inputs feature provides a method of performing checks on the function of all contact inputs.While in Forcible test mode, the relay contact inputs can be pre-programmed to respond in the following ways:• If set to “Normal,” the input remains fully operational. It is controlled by the voltage across its input terminals and canbe turned on and off by external circuitry. Select this value if a given input must be operational during the test. Thisincludes, for example, an input initiating the test, or being a part of a user pre-programmed test sequence.• If set to “Open,” the input is forced to report as opened (Logic 0) while the operand selected by TEST MODE FORCINGsetting is On, regardless of the voltage across the input terminals. While the selected operand is Off, the input behavesas it does when in service.• If set to “Closed,” the input is forced to report as closed (Logic 1) while the operand selected by TEST MODE FORCINGsetting is On regardless of the voltage across the input terminals. While the selected operand is Off, the input behavesas it does when in service.5.11.5 Force contact outputsSETTINGS TESTING FORCE CONTACT OUTPUTS PMU 1 IG TESTANGLE: 0.00°Range: –180.00 to 180.00° in steps of 0.05 PMU 1 TESTFREQUENCY: 60.000 HzRange: 20.000 to 70.000 Hz in steps of 0.001 PMU 1 TESTdf/dt: 0.00 Hz/sRange: –10.00 to 10.00 Hz/s in steps of 0.01 FORCE CONTACT INPUTS FORCE Cont Ip 1: NormalRange: Normal, Open, Closed FORCE Cont Ip 2: NormalRange: Normal, Open, Closed FORCE Cont Ip xx: NormalRange: Normal, Open, ClosedOn restart, the TEST MODE FORCING setting and the force contact input and force contact output settings revert totheir default states.
